Why our Vert Junkies® love this

This is the layer that starts the whole system. 100% merino wool. Midweight warmth with a 1/4 zip to dump heat on the move. Odor resistance, breathability, and moisture control—locked in.

Key Features

  • 100% Merino Wool knit construction

  • Midweight build: balanced warmth + airflow for mixed-output days

  • 1/4 Zip Neck for fast temperature regulation without stripping layers

  • Breathable + moisture-wicking performance to manage sweat spikes

  • Odor-resistant merino for multi-day wear and repeat laps

  • Next-to-skin, athletic fit with high stretch (size down for a tighter fit)

Recommended Use

Wear it solo for cold-weather training, or run it under a shell for ski days and windy ridgelines. Zip up for the chairlift. Zip down when the climb turns savage.

Bottom Line

Merino heat. Zip control. Zero excuses.
